Area Code 463 Location

Area code 463 serves Carmel, Indiana, and the greater Indianapolis metro in central Indiana. It’s an overlay for the long‑standing 317 area code, so the same geographic region uses both codes for local phone numbers. Carmel sits just north of Indianapolis in Hamilton County, a busy hub for business, healthcare, and tech. With the overlay, residents and businesses use 10‑digit dialing for local calls, helping the region add new numbers without changing existing ones.

Major communities covered by the 317/463 overlay include:

• Indianapolis
• Carmel
• Fishers
• Noblesville
• Greenwood
• Zionsville
• Westfield
• Lawrence
• Plainfield
• Brownsburg

The 463 area code was introduced in 2016 to relieve number exhaustion in the fast‑growing Indianapolis area. Existing 317 phone numbers stayed the same, while new lines may receive 463, especially in places like Carmel and neighboring suburbs. A helpful trivia note: on a phone keypad, “463” spells IND, a nod many link to “Indiana.” Landmark highlights within the coverage area include the Indianapolis Motor Speedway, Monument Circle, and the Carmel Arts & Design District. Since the overlay began, the region has kept familiar numbers while supporting steady growth in mobile phones, businesses, and connected devices.

“An overlay occurs when a new area code is assigned to the same geographic area as an existing area code.” — North American Numbering Plan Administrator (NANPA)
